Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68750, here are decompositions:
- 7 + 68743 = 68750
- 13 + 68737 = 68750
- 37 + 68713 = 68750
- 67 + 68683 = 68750
- 139 + 68611 = 68750
- 211 + 68539 = 68750
- 229 + 68521 = 68750
- 277 + 68473 = 68750
Showing the first eight; more decompositions exist.
